Prepare boxed brownie mix as directed. Spoon batter evenly into mini muffin cups. Bake for 13-15 minutes or until top is set and a toothpick inserted in the middle comes out slightly wet. After brownies are out of the oven, wait for the centers to fall. This will happen upon cooling. If not, then tap the centers with the back of a teaspoon to make a dipped in spot for the peanut butter.

Place peanut butter in a small microwaveable bowl. Microwave on high for about 35 seconds and then stir. While the brownies are still warm spoon about half a teaspoon on peanut butter into the center of each brownie. Top with semi sweet chocolate chips and peanut butter chips.

Cool completely in pan. Go around the edge of the brownies with a knife and they should pop right out!
